This study was carried out to determine the effects of Mangan-Desferrioxamine (Mn-DFX) and Verapamil (VRP) in 7,12-dimethyl-benz-[a]anthracene (DMBA) induced mammary carcinoma. 70 Spraque Dawley rats were divided into four groups; as DMBA alone, DMBA + Mn-DFX, DMBA + VRP, and control. Incidence, multiplicity, and size of tumors were evaluated in addition to analyses of DNA ploidy status and proliferation index by flow cytometric technique. The results revealed that Mn-DFX and VRP caused significant decreases in tumor incidence (p < 0.02 and p < 0.05), multiplicity (p < 0.02 and p < 0.05), size (p < 0.05 and p < 0.02), and proliferation index (p < 0.05 and p < 0.02) without any toxic effect. The appearance of first tumors in Mn-DFX and VRP groups was also later than in the DMBA alone group (10th and 11th week versus 6th week). In conclusion, Mn-DFX and VRP have offered prevention in experimental mammary carcinogenesis. These agents caused slower tumor growth, though they could not achieve a complete prevention.
Sixty gunshot injuries in 48 patients were treated in Mobile Surgical Hospital (30-bed capacity) of the Mountain and Commando Brigade in Hakkari, Türkiye, between May 1990 and May 1991. The David Sisk method was used for the classification of the injuries. Eleven type 1 injuries were treated conservatively, 39 type 2 and 10 type 3 injuries were treated by extensive debridement with suction drainage and primary closure. No infection was seen in type 1 injuries. The infection rate was 2.56% in type 2 and 20% in type 3 injuries. The following results were obtained: type 1 injuries must be treated by conservative measures; type 2 injuries must be treated by primary closure following extensive debridement and suction drainage; type 3 injuries can be treated by extensive debridement with suction drainage and primary closure.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
